SERVICE ENTRANCE CAP.

Application filed August 29, 1916.

To all whom it may concern.

Be it known that I, CARL H. BIssELL, a citizen of the United States, anda resident of Syracuse, in the county of Onondaga and State of New York,have invented a certain new and useful Service Entrance Cap, of whichthe following is a specification.

This invention has for its object a box for use in connection withelectric conduits, and. what is called for convenience, a servicentrance cap, as it is mounted upon the upper end of a conduit throughwhich the service wires are led into a building or other structure,which service entrance cap is simple in construction and highlyeflicient and durable in use. The invention consists in the novelfeatures of construction hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure 1 is an elevation of a preferable form of my service entrancecap, the contiguous portion of an electrical conduit being also shown.

Figures 2 and 3 are inner face views of the top section and the lowersection of the cap, with nipple attached thereto.

Figure 1 is a Vertical section view of parts seen in Fig. 1.

This cap consists generally of upper and lower sections separable alonga plane extending generally, in a horizontal direction and confiningwire passages between them, the lower section being provided with meansfor connection with the conduit, and means for holding the sections fromseparation.

1. and 2 designate the upper and lower sections which are usually formedof an insulating compound. the upper section having a rounding topsurface for facilitating the shedding of water, this top surface merginginto a peripheral vertical cylindrical surface 3 at the rear of the cap.The section 1 is in the form of an overhang or hood at 4 at its frontend, the sections 1 and 2 having an under surface 5 at their front ends.

The section 1 is formed with a shallow recess 6 and with grooves 7 inits lower face, the grooves leading from the recess 6 and openingthrough the under surface 5; and the lower section 2 is formed with ahub or annular flange 8 extending into the recess and fitting the sidewalls 9 thereof, and with Serial No. 117,433.

grooves 10 complemental. to the grooves 7 and therewith forming wireholes.

The lower section is also formed with a bearing face 11 around. the hub8, and on which rests the flat surface 12 of the section 1 around therecess 6 and between grooves T. The lower section 2 is also providedwith a. vertical passage 13 arranged concentric with the hub S.

14 is a metallic nipple, the body of which fits into a counter bore atthe lower end of the passage 18, said nipple being internally threadedfor receiving the threaded end of an electrical conduit 15.

The means for holding the sections 1, 2 from separation, comprises meanswhich coact with the top section 1 and the nipple 14 to clamp saidsection 1, and nipple on the upper and lower sides of the section 2. Ashere illustrated, said section 1 and the nipple 14 are clamped togetherby screws 16 extending vertically through laterally extending ears 17,'18 provided on the section 1 and the nipple let, these screws 16 beingindependent of the section 2 and located outside of the periphery of thesection 2.

In operation, the nipple 14 is first screwed into the top of a pipe andthe wires passed through the passage 13 of the section 2 and into thepipe whereupon the section 2 can be placed on the nipple and finally thetop section 1 placed in position and the parts clamped together by thescrews 16.

Owing to the fact that the sections 1, 2 separate along a horizontallyextending plane, the wires can be easily manipulated in the pipe andfurther owing to such separation of the sections 1, 2 and to the boss 8fitting into the recess 6, and to the bearing surfaces 11, 12 and to thearrangement of the wire holes, the cap is water tight.

\Vhat I claim is:

1. A service entrance cap comprising an upper cap section, a lowersection formed with a vertical passage therethrough, an attaching nipplebelow the lower section and separable therefrom, and means for clampingthe top section toward the nipple, said means being independent of thesecond mentioned section, substantially as and for the purposespecified.

2. A service entrance cap comprising upper and lower sections separablealong a plane extending in a general horizontal, direction, andconfining a wire space and pasing beyond the outer surface of the lowersec- 10 tion, and eh'un iing members extending through said. ears,substantially as and for the purpose set forth.

In testimony whereoi 1' have hereunto signed my name, at Syracuse, inthe county '15 oi Unondzw'u, and State of New York, this 5th day oi:June 1916.
